Rolls-Royce has concluded a 13-year service contract with Canadian mine operator Barrick Gold Corporation. The agreement covers regular maintenance of the 30 MTU Series 4000 engines in operation in Hitachi dump trucks at the Lumwana copper mine in Zambia. To ensure fast, trouble-free service, more than 10 MTU employees will be stationed directly on-site at the mine. The MTU brand is part of Rolls-Royce Power Systems. Dan Gray, Maintenance Manager for Barrick Gold Corporation at Lumwana, said, ?Everyday mining operations are a hard business ? for us and for the engines. That means we must be able to count on things running without a hitch. To make sure that happens, we opted for the reliability of the service provided by MTU.?
